cfittft 11 The invention relates to electronic supermixing devices and can be used in analog computers. A device for a multiplier is known, which contains voltage transducers to pulse frequency, pulse counters, control unit1:.: 1 1. However, this device is characterized by low accuracy when operating in a wide range of input signals. The multiplier device containing connected in series is the closest one. the first voltage to pulse frequency converter and pulse counter, the second voltage to pulse frequency converter, the output of the cat-th through the interval interval conversion unit row pulses in voltage is connected to the control input transducer pervog voltage in pulse frequency 2 j. A disadvantage of this device is the low accuracy of operation in a wide range of input signals due to the peidepticity of the parameters of the voltage to frequency converters. The purpose of the invention is to increase the accuracy of work. The goal is achieved by the fact that the device for multiplying, containing the first and second voltage converters to the frequency of the pulses, whose inputs are the first and second inputs of the device, respectively, the output of the first voltage to frequency converter is connected to the information input of the pulse counter, the output of which is the output of the device, a synchronization unit and a hyperbolic pulse duration converter are inputted, the output of the second transforming the voltage body into the pulse frequency p Connected to the trigger input of the syncronization unit, the first output of which is connected to the information input of the hyperbolic pulse width converter, the output of which is connected to the pulse input of the pulse counter, the installation input of the initial state of which is connected to the clock input of the hyperbolic pulse width converter and with the second output block sync. FIG. 1 shows a functional diagram of the proposed multiplication device, FIG. 2 shows time diagrams of signals. The device contains .the first 1 and second 2 voltage-to-pulse frequency converters, a pulse counter 3, a synchronization unit 4, a hyperbolic transducer 5 of pulse duration, the first 6 and second 7 inputs and an output 8 of the device. Hyperbolic transducer 5 pulse duration can be performed, for example, in the form of serially connected. the two integrators and comparator, the second input of the comparator and the input of the first integrator are connected to a reference voltage source, the second input of the first integrator is an information input, and the reset inputs of the integrators and comparator are connected and are a clock input of the hyperbolic converter. The multiplier operates as follows. At the outputs of the first 1 and second 2 voltage to pulse converters, linear pulse sequences are formed: f .-- 5.x. (1 de - transform steepness, Ujj, and - voltage on the first 6 and second 7 inputs. Pulse sequences are received at the information input of the 3-pulse counter and the input of synchronization unit 4 (Fig. 2a, b). At the first output of the synchronization unit, an impulse is generated aprons (fig.26, duration Tg .., frequency period (2)), avnoi. This impulse goes to the information input of a hyperbolic transducer 5 pulse width, at the output of which a voltage pulse is formed (fig.2g) with a duration back proportional length pulses at its input 1 Vix T where K is a proportionality coefficient. This pulse arrives at the clock input of the counter of 3 pulses, opening it for the duration of the action. As a result, the number of pulses is recorded in the counter of 3 pulses

Such a device for multiplying allows the use of voltage to pulse converters with a lower dynamic range while maintaining the dynamic range of the device.

Compared with the prototype device, the proposed multiplication device is characterized by a more high precision of operation due to the mutual use of the same voltage to pulse frequency converters.
